The most serious claim against Michael Flynn seems to be that he lied to the boss. That's pretty bad. But the prospect of his having spoken to the Russian Ambassador about sanctions isn't that impressive, at least to this outsider, considering all the things Democrats have done.
Conspiracy theorist are in full battle mode. But the one thing no one is talking about is whether there may be a lot more to what Flynn was into than what we've heard. Maybe he's a mole. Or maybe the KGB has some genuine blackmail grade dirt on him.
Mitch McConnell is threatening to investigate. Maybe he can get to the bottom of it. Then maybe someone who wasn't in Obama's pocket can justify the witch hunt against Flynn.
